My screenshots seem to have stacked in order to demonstrate my steps.
I tried to attach my guy Oscar Daum from line 64. He didn't show up when I searched Historical Records, so I had used the waypoints from Ancestry and browsed to the image at FamilySearch.
When I control-click the notepad icon to see the index entry in a new tab, only his details appear and not his wife Lisette's.
When I control-click "Attach" to go to a new tab, his name appears on the left as both himself and his wife. The popup Possible Matches/History List recognizes him as my target from the tree (ID GVZG-C4X), so I click "Select."
After clicking "Select" the popup disappears, but nothing else happens, as if the system froze. None of Oscar's details from the tree populate on the right
Oscar is causing trouble on the 1950 census too. I reported him separately for that.
